Efficient & Industrial-Grade
Compressed Air Dryers

Dramatically reduce the moisture content in your compressed air system by implementing a compressed air dryer from Gardner Denver. Whether you need a primary source of air drying for your compressed air or a secondary source, Gardner Denver has both refrigerated and desiccant air dryers.

Saturated air can wreak havoc on production and manufacturing processes. Removing the liquid from the system can be a high energy consumption area if not managed properly. Each Gardner Denver compressed air dryer was designed to remove the moisture from your compressed air system while consuming less energy with their energy saving features.

Gardner Denver has many options when it comes to refrigerated compressed air dryers. Choose from models that are cycling or non-cycling units, rated for high pressure, temperature or capacity and more.

Need a desiccant air dryer for your compressed air system? See all the models Gardner Denver has to offer, everything from externally heated systems to dual tower models to blower purge systems and more.

How Does a Compressed Air Dryer Work?

Compressed air dryers remove moisture content from compressed air. Moisture in compressed air can create issues for the tools, machinery and equipment that utilize the air. Although they all perform the same basic tasks, there are many different types of compressed air dryers. Each type has a different way of achieving moisture reduction.


Refrigerated Air Dryer

The refrigerated air dryer functions by cooling the incoming compressed air and extracting and draining the moisture. Refrigerated air dryers account for a majority of the compressed air dryer applications. There are two variations of refrigerated air dryers, cycling units or non-cycling units.

Cycling units automatically cycles the refrigeration compressor on and off in response to the inlet load conditions. They are better suited for conditions where the inlet load is not constant. The ability to cycle on and off products considerable energy saving benefits.

Non-cycling units continually operate with the refrigeration compressor on, regardless of the load coming in. This style of compressed air dryer is ideal for situations where a consistent dew point is needed for operations.


Desiccant Air Dryer

With desiccant air dryers, the process of drying occurs by the compressed air traveling through a towers that contain a drying agent, the drying agent removes moisture through absorption and the drying process switches from one tower to the other with the system blowing the drying agent dry.

There are numerous styles of desiccant air dryers, including heatless, externally heated, blower purge and dual or single tower setup.

In many cases, it is ideal to have both a refrigerated air dryer and desiccant air dryer working in tandem, with the refrigerated dryer as the primary source and the desiccant dryer as the secondary.

Incoming air in all compressed air systems will have a dew point level that you need to manage properly. By selecting the right combination of air treatment equipment, including compressed air dryers, you can minimize moisture levels and deliver clean, dry compressed air.
